From my discussions with others, it looks like DHCPv6 PD is the standard replacement for DHCP with IPv6 between one's router and the ISP. My router runs OpenBSD and I currently have both SLAAC and DHCPv6 set up on it with a static prefix (a /48) from Hurricane Electric.

When I get a native IPv6 connection, I'm going to have to set up DHCPv6 PD with both rtadvd and DHCPv6 (currently WIDE-DHCPv6), but the documentation there is pretty sparse. Does anyone here know how set that up?

Few project developers frequent this site as most (regulars) are users, enthusiasts, & others interested in OpenBSD. I don't recall anyone professing using IPv6 yet, although there may be fledgling knowledge.

You may also want to consider searching the project's official misc@ mailing list, as this was discussed within the last six months.

Hmm. The only relevant result I see in MARC's openbsd-misc results (I can't post the URL because I don't have enough posts here) is about having a static /48 prefix and using a single /64. I already have that working with Hurricane Electric, which doesn't help me if Comcast goes with DHCPv6 PD.
